This problem here is something I've addressed in the past. The '05
version that we got from Josh Grahms didn't include a 5:6:5 routine
that converts the 32 bit color codes that we are all used to using
into the 565 color format that the 4117hex vesa requires.

Adding this routine to an '05 image that is running in 4117 vesa will
allow the '05 user to run everybody elses code unchanged in the
display.

Obviously I don't think this is the sizeing problem you are having with 2.0a.

Is it convenient to have block 30 be different from the rest of the
world by redefining the colors there? I think it's easier to add the
5:6:5 code to the kernel and then be done with it. YMMV :-)
